Alright, let's solve this math problem step by step. First, we have the number 353. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 9. So, we're going to take the number 353 and add it to itself 9 times.
Step 1: 0 + 353 = 353
Step 2: 353 + 353 = 706
Step 3: 706 + 353 = 1059
Step 4: 1059 + 353 = 1412
Step 5: 1412 + 353 = 1765
Step 6: 1765 + 353 = 2118
Step 7: 2118 + 353 = 2471
Step 8: 2471 + 353 = 2824
Step 9: 2824 + 353 = 3177

So, 353*9 = 3177
